Essential wired video doorbell - connecting to 1940s door chimes

[TBracy]

Does anyone have any experience knowledge connection the wired doorbell to a 1940s tubular door chime similar to this?  https://www.electrachime.net/long-bell-chimes/post-1950-tubular-doorbells/rittenhouse-lyric-sheraton...

The door chimes are a Rittenhouse builders model 375. With two, (a 40" and a 34") one inch diameter brass tubes.  There are 2 plungers in the steel housing that strike the tubes when the doorbell is rung. The plungers are connected to a small transformer.

I'd like to be able to have the door chimes still work if possible with the camera connected.

What are the specs for the transformer?

I unfortunately do not know and am not sure how to figure that out.

Is there a part number or label on the transformer?  If you can see it, try posting a photo.
